Realism argument? If you want to pick apart realism vs unrealistic aspects of the video game, I believe the outcome would heavily weigh in favor of the latter. I don't know how to quote a previous post by someone, but I remember you arguing realism wasn't a valid reason for Hip-Firing being less accurate. Seems you are arguing both for and against realism when it suits you.
Edit: I went back and looked, the discussion is on p.21 of the Destiny Alpha Withdrawal thread (last post on page). Everyone is entitled to their opinions, but arguing against cleavage because it is "unrealistic", then invalidating realism regarding ADS (in the same game, no less) is hypocritical.
